PITTSBURGH -- Carnegie Mellon University researchers are relying on an old adage to develop anti-fraud software for Internet auction sites: It's not what you know, it's who you know.
At sites like eBay, users warn each other if they have a bad experience with a seller by rating their transactions. But the CMU researchers said savvy fraudsters get around that by conducting transactions with friends or even themselves, using alternate user names to give themselves high satisfaction ratings _ so unsuspecting customers will still try to buy from them.
